I am a few days late to this thread, but I spent significant time
recently trying to ascertain the answer to the original post.  While I
went the Vista Ultimate 64 route as it has the maximum 128GB memory
capacity, as already mentioned, others are as little as 8GB - for more
on this and Vista 64 version RAM limitations see:

http://compreviews.about.com/od/memory/a/Vista4GB.htm

My choice of Vista 64 had little to do with Stata and most to do with
how little I could find on XP 64.  It was never released as a retail
product and you have to buy an OEM copy similar to those who construct
machines themselves on sites like Newegg.com.  Further, most of the
article links I could find regarding XP 64 on Microsoft's site were
dead.  There was a technical guide on choosing XP 64

http://download.microsoft.com/download/B/8/6/B868C664-13FC-4F91-9651-5B6D4F1A2F60/Is_Windows_XP_Professional_x64_Edition_Right_for_Me.doc

which was helpful - and I believe will be helpful for potential Vista
64 adopters - in that I concluded the main issue (besides my
continuing uncertainty regarding whether one can simply buy the OEM
version and install it over an existing operating system etc.) was
driver support.  With all the links non-functioning on Microsoft's
site I concluded that installation could be a nightmare, particularly
as I have never put a machine together from scratch, so have no
experience driver hunting and working through glitches when drivers do
not work.  Thus I purchased a machine from HP with a recent quad-core
CPU and 8 gig of RAM with Vista Ultimate 64.  I did not pursue buying
a built XP 64 system since I like to use Costco/Costco.com for PC
purchases given the excellent warranty and support (90 days no
question refund and 2 years telephone concierge service which I have
gotten good use of in the past).  I just took delivery of the Vista 64
machine this past week and am still configuring it.  I have purchased
a Stata SE 10 64 bit version and hope to install in the next day or
so.

If anyone has XP 64 and Stata 10 SE, I would be happy to run any tests
for comparison, etc.
